摘要
山区农村供水区域地势变化大,配水管道和村级管网相应起伏变化较大。文章以张家川回族自治县农村饮水工程为背景,简述了比例式减压阀工作原理及特点,分析了实际应用效果。实践证明:该阀从根本上解决了农村供水高压差比的问题,延长了管道使用寿命,具有有效性和稳定性,在农村供水中发挥了不可替代的作用,值得在山区和丘陵地区农村供水中推广应用。
The terrain of rural water supply area in mountainous area is changed greatly.Corresponding fluctuation of water distribution pipeline and village-level pipe network is changed greatly.The working principle and characteristics of the proportional pressure reducing valve are described briefly,and the practical application effect is analyzed based on the background of rural drinking water project of Zhangjiachuan Hui Autonomous County.Practice shows that the valve can be used for fundamentally solving the problem of high-pressure difference ratio in rural water supply,and prolongating the service life of pipelines.It has effectiveness and stability,which plays an irreplaceable role in rural water supply.It is worthy of popularization and application in rural water supply in mountainous and hilly areas.
